A few months back I noticed an interesting interaction between how direct eval
is defined and multiple globals. What happens if, in one global, you call an
eval from another global as if it were a direct eval?
var indirect = otherGlobal.eval;
eval = indirect;
print(eval(this) === this);
Jeff,
I think your real question reduces to this:
//none strict mode code
globalObj= function() {return this}();
print(otherGlobal.eval(this) === globalObj) //??
The two different calls and the indirect name in your example may make the
question seen like it is about something else

If we're saying that Harmony is strict-only, settable by a script tag, what
will indirect eval and the Function constructor do if the evaluated code
doesn't start with a use strict directive?
Yeah, strict-only is probably not quite the

I've written that Harmony is based on ES5 strict. But even ES5 strict code can
call non-strict code. Same goes for Harmony. It's a big shared-heap

Yikes... not playing who-said-what. For whatever reason, Waldemar got the
impression that someone said it, and I'm correcting the misconception, that's
all.

Hi Jeff,
I agree that the spec should deal with multiple global objects. I'm aware of a
few of the subtleties of multiple globals, but I wouldn't be surprised if there
are more. Thanks for raising this one. I created a placeholder strawman last
week, because I've been intending to get into
10 matches
